recommend a mat to put underneath my bike trainer

[mattkime]

i got a complaint from a neighbor about the noise (when i'm on my game i get started at 7am). The fact that my alcoholic neighbor is apparently a light sleeper seems ridiculous but whatever.

i'm looking for a rubber mat that absorbs vibration from the trainer. i'd prefer something smaller - it doesn't need to cover the whole footprint of bike + trainer, jsut the trainer itself.

this is the trainer i have - http://www.amazon.com/Kinetic-Rock-Roll-...dp_product



any advice?
